TracBack Navigation/
MOB: Man OverBoard
• If the track log interval is set to the ‘Time’ option, the route may not follow your exact path (keep
the interval set to ‘resolution’ for best performance).
• If the receiver is turned off or satellite coverage is lost during your trip, the TracBack will draw a
straight line between any point where coverage was lost and where it resumed.
• If your track log’s changes in distance and direction are too complex, 50 waypoints may not mark
your path accurately. The receiver then assigns the 50 waypoints to the most signifi cant points of
your track, and simplifi es segments with fewer changes in direction.
To stop TracBack navigation:
1. Press the NAV key, highlight ‘Stop Navigation’ and press ENTER/MARK.
For more information on setting up the Track options and saved tracks, see pages 59-60.
